Abstract

The quality and quantity of nutmeg fruit, seed and mace can be improved through managing fruit and seed production.  Fruit development was affected by climate, flower initiation and pollination process. This study aimed to determine the correlation between climate, position, distance of pollen donor to female nutmeg trees, and the ratio of female and male trees to nutmeg yield.  The study was conducted at the nutmeg germplasm collection garden at Cicurug (550 m asl), Sukabumi, tested 295 nutmeg trees from 27 locations in Indonesia. Data production of female trees was based on 2005-2017 data. All nutmeg trees were mapped using the GPS Garmin 76c5x.  Tree sex was determined by male or female flowers domination in each tree. Correlation of the climate factors and production was analyzed using Pearson Correlation. The distance, position and the proportion of female to male trees were evalated by t-test at 5% level.  Ratio of female and male trees to produce high yield was 4 : 1. Rainfall (280-430 mm/month) and temperature (24 - 25o C)   during  the  pollination  period  (8-7  months  before  harvesting)  were positively correlated with production by 57.9 % and 82.3 %. The position and distance of pollen donors to female trees had no effect on production.  However, the distance between pollen donors and female trees above 15 m produced an average production equal to 15 m. The number of trees around tree samples had no effect on nutmeg production, but light intensity at 61,425-88,480 lux absorbed by trees could enhance the yield.  Nutmeg required sunlight to penetrate plant canopy in order to induce fruit production.

Abstract

The evaluation of growth, productivity and quality of 15 accessions of Ceylon cinnamon (Cinnamomum zeylanicum Blume) at the medium elevation in Laing Research Installation Solok West Sumatra, has been conducted from January 2007 to April 2013. The experiment was arranged in Randomized Block Design with 15 treatments (accessions) and repeated three times. Parameter observed were plant height, stem diameter, number of branches, bark thickness, bark production, leaf production, oil yield and components of oils. The results showed that, the highest plant height was Czl16 (497.67 cm) and Czl30 (478.33 cm). The largest stem diameter was Czl16 (12.33 cm) followed by Czl15 (11.33 cm) Czl02 (11.00 cm) and Czl29 (11.00 cm). The highest branch number was Czl30 (30.00), Czl15 (29.00), Czl22 (29.00) and Czl35 (28.66). The highest production of dry bark was Czl30 (4,350 g.treeˉ¹) and the lowest one was Czl03 (1,800 g.treeˉ¹). The highest leaf production was Czl15 (18,700 g.treeˉ¹ and Czl16 (18366.67 g.treeˉ¹), and the lowest one was Czl03 (7,633.33 g.treeˉ¹). The highest of oil yield was Czl12 and  Czl30 0.75 %  each  and the lowest one was Czl11 (0.27 %). The highest of  cinnamaldehyde content was Czl35 (61.24 %), followed by Czl22 (59.38 %) and the lowest one was Czl17 (37.78 %). The chemical components of oils of cinnamon bar analyzed by GCMS from Czl35 accession consisted of 51 components and the primary components were cinnamaldehyde 61.29 %, eugenol 6.87 %, β-caryophyllane 6.59 %, cinnamyl acetate 5.61 %, β-phellandrene 4.79 %, dillapiole 3.39 %, benzoic acid 1.82 %, Linalool 1 %, and 43 other components each below 1 %.
